Grafton Resources Begins Geophysical Survey at Alicahue Gold-Copper Project in Chile

Vancouver, British Columbia — February 12, 2026 — Leads & Copy — Grafton Resources Inc. (CSE: GFT; OTCQB: GFTFF; FSE: K8L0) has announced that Expert Geophysics Surveys Inc. has commenced an 80 line-kilometre mobile magnetotelluric (“MobileMT”) heliborne survey at the Alicahue Gold-Copper Project in Valparaiso, Chile.

The survey will cover the entirety of Grafton's Alicahue Gold-Copper Project and interpreted results are expected in March 2026.

MobileMT is a geophysical technology used to identify subsurface geologic structures, alteration halos and contrasting lithologies. Complementary VLF-EM data is expected to provide increased resolution of shallow features.

The combined methods should identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to a depth of approximately 1 km to 2 km, depending on the conductivity distribution of the local geology.

Campbell Smyth, Chairman of Grafton Resources, said that the company expects the Mobile MT data will provide a three-dimensional image of the Alicahue Project area. He hopes the survey will assist in tracing the outline of a possible porphyry centre in the southeast concession and vector towards the origin of the IOCG vein systems and possible feeder zones to gold and copper vein mineralization mapped in the area.

Smyth added that MobileMT is known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres, and resistive bodies representative of intrusions.

Grafton Resources is a Canadian exploration company listed on the Canadian Securities Exchange (CSE), focused on the discovery and development of mineral assets in the Americas.
